Remarks

The SpeechRecognizer class should only be used if you wish to display a custom graphical user interface (GUI) in your app. Otherwise, use the SpeechRecognizerUI class for speech recognition that includes a default GUI which is uniform across apps and utilities.

If a SpeechRecognizer instance is instantiated and no grammars have been loaded, the speech recognizer performs speech recognition against the pre-defined dictation grammar.
